[Mailman-Users] Virtual host with "manual" MTA?

[Tim Bingham]

Greetings all,

First-time poster here. I have Mailman 2.1.5 that has been running 
great for years on an older Solaris 8 server. I received a request to 
create a list using a host name that's not the actual host name of 
the server. Let's say the server is "lists.university.edu" and the 
requested list name is "listname at lists.project.org".

I read up what I could find (and understand) about virtual hosts and 
I was able to successfully create the list with the alternate host 
name, configure Apache to have a virtual host pointed to the web 
interface for that list, and I added a domain to our DNS and set up 
the host name there. I can subscribe to the list and post to it using 
the virtual host name, but email coming out from the list has the 
real host name as the reply address.

Everything I've read mentions configuring Postfix for virtual hosts. 
However, I'm not using Postfix - my Defaults.py has MTA = 'Manual' 
and DELIVERY_MODULE = 'SMTPDirect'.

Is there anything I can do to get the list to use the virtual host 
name for a reply address on outgoing email without installing and 
using Postfix? I have no experience with it and am trying to keep it 
simple.

Thanks for any help you can offer,
Tim
